We present the ultrafast imaging of thermal-energy chemical dynamics of micro-solvated (bio)molecular complexes when probing with strong-field techniques. We produce a pure sample of the molecule of interest in the gas phase by using a combination of a molecular beam and electrostatic deflector [1]. To study the thermally-induced dynamics, we set up a mid-IR pump-probe experiment, in which a 3 µm beam was used to excite the system and then a 1.3 µm nm beam was used for ionising the system. First experiments focus on the ion-imaging of the mid-IR pumped system. Future experiments will use laser-induced electron diffraction (LIED) [2,3] to probe the thermally-induced dynamics and obtain structural information about the system with atomic resolution.
